WASHING APPARATUS.

Specification of Letters Patent.

Patented May 1 1, 1918.

Application filed December 31, 1917. Serial No. 209,807.

To all whom it may concern.-

Be it known that I, OTTO SPEEHR, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Washing Apparatus, ofwhich the following is a specification.

This invention relates to a device used in connection with washingmachines, and embodies a new apparatus for preparing liquid or solutionfor washing purposes.

It is well known that the material going to laundries to be washed isoften in need of disinfecting as well as cleansing, and the presentinvention provides means for accomplishing these purposes.

Specifically, it provides means for introducing a disinfecting vapor,such as a vapor of kerosene, into a washing machine, under high pressureand temperature, whereby it is thoroughly distributed through all partsof the washing liquid.

In addition to its disinfecting action, kerosene vapor has a cleansingaction, and also serves to preserve the parts of such machincry.

The invention embodies a vaporizer and an atomizer connected thereto,and associatcd with an injector which is operated by steam and deliversthe vapor in a finely divided condition to the hot water supply of thewashing machine.

The accompanying drawing is a sectional view of the apparatus.

Referring to this drawing, 6 indicates a vaporizing tank of considerablecapacity. This is inclosed by steam jacket 7 to which steam is suppliedthrough an inlet 8, having an outlet 9 at the bottom which may lead toto a trap. Kerosene or other disinfecting fluid may be poured into thetank through a pipe 10 at the top, and water pressure may besuppliedthrough a pipe 11 at the bottom, which also serves as a drain.

The pipe 10 is provided with a vapor outlet pipe 12 having a check valve13 therein, and connected to the bottom of a receiving tank or vessel 14of relatively small capacity. This vessel is connected to an injector bya pipe 15 which dips into the vessel to nearly the bottom thereof.

The injector comprises a casing 16 which may screw into the neck of thetank, and in this casing 16 is a nozzle 17 supported by a partition 18,the whole forming a passage leading from the pipe 15 to the annularspace around the jet nozzle 17. Steam under pressure is supplied to theinjector through a pipe 19 controlled by a valve 20, and there is apassage 21 leading from the inlet side of the injector casing through asmall port 22 into the top of the tank 11- so that the vapor in the tankis under pressure. The discharge outlet from the injector is connectedby a pipe 23, having a valve 24, to a water supply pipe which leads tothe washing machine not shown. The valves 20 and 2-1 are connected by alink 26 so that they open and close together. A three-way valve 27controls the filling pipe of the vaporizer tank 6, and the outlet to theconnecting pipe 12.

In the operation of the apparatus kerosene or other disinfecting liquidis put in the tank 6, and put under some pressure through the pipe 11,as by water admitted to the tank. Steam is admitted to the surroundingjacket and the kerosene is thereby vaporized, and this vapor is forcedthrough the pipe 12 into the receiver 1 1. By opening valves 20 and 2%the injector acts to draw the vapor from the receiver and it is entrained by the steam jet and discharged at a high velocity into the hotwater supply pipe and passes thence to the washing machine. The injectoraction is assisted by the steam pressure admitted from the steam linethrough the port 22.

The water thus supplied to the washing machine becomes impregnated withthe vapor of kerosene and this has a disinfecting action on the materialbeing washed and also serves to save soap, as suds are much more easilyproduced in water charged with kerosene vapor. The vapor being ,.,in ahighly heated condition mixes readily and effectively with the water,and is much superior to any attempted mixing of the same when in liquidform.

When the injector action is stopped the receiver 14: will be refilled byvapor forced from the vaporizing tank by the pressure admitted thereto.

The invention is not limited to the particular apparatus shown, but maybe modified in various ways.

I claim:

1. In a washing apparatus, the combination of a heated vaporizer for adisinfecting or cleansing agent, and an injector connected vaportherefrom into a washing machine.

In a washing apparatus, the combination of a heated vaporizer for adisinfecting or cleansing agent, a tank for vapor connected thereto andan injector connected to the tank and adapted to inject vapor therefrominto a tater supply to a Washing machine.

The combination of a vaporizer, a re eeiver connected thereto, aninjector havng a steam supply pipe thereto and connected to a vvatereupply line, and a branch passage from the steam pipe into the receiverto heat the vapor therein and naintain same under pressure.

n The eoinhination of a heated vapor-is: r, a vapor pressure tankconnected thereto, a, oheek valve between the vaporizer and the Copiesof this patent may and adapted to injectfinid therefrom into 2 WaterSuppl".

5. In a Washing apparatus, the combination of a vaporizer disinfectingor cleansing agent, provided with means to create pressure therein, atank for vapor connected thereto and adapted to be supplied with vaportherefrom in consequence of such pressure, and means to inject vaporfrom said tank into a Washing machine.

In testimony; whereof 1 afiix my signaturein presence of f -witnesses.
